Extinction and What We Eat
Food & The Environment
Essential Questions• What is the relationship between food production and
extinction?• What is the impact of food production on the
environment? • What is the correlation of human population with fish
stocks and meat production?• How does human population impact agriculture? • How do different types of food production differ in
impacts on extinction and climate?
Objectives
• Describe the relationship between food production and extinction.
• Use data to show environmental impacts of modern agriculture.• Demonstrate the correlation of human population with fish
stocks and meat production.• Illustrate how human population impacts agriculture.• Show how types of food production differ in their impacts on
extinction and climate.
Favorite Foods!
What is your favorite food?
Write a list of your three favorite foods.
What could you do?
What are three things you could do to prevent destruction of our oceans?
Think of daily activities that may have a wider impact on our oceans.
Could you eat differently?
Would you change your diet to save the oceans?Use your food logs to create a sample
menu of what you eat in one day.
Understanding Food
You will learn about how food production affects the environment
and Earth’s wildlife.
How Much Do You Eat?
Use your food logs to estimate your annual animal protein consumption.
Consider…• Units to quantify consumption:
– Biomass– Calories– Soil and water
• Including dairy as well as meat and fish
Impacts of Modern AgricultureWith your group:
Research evidence for the environmental impacts of modern agriculture.• Create a graphic organizer showing environmental impacts
Use maps to explore impacts:• Habitat loss• Carbon dioxide emissions• Pollution• Decline of crop diversity• Soil erosion
Impacts of Modern Agriculture: Resources
Explaining Food ProductionWith your group:
Present your graphic organizer to the class.• Explain your conclusions• Describe other ways you could collect data• Discuss the scientific method
Your discussion should include:• How the scientific method can be used to address complex questions about:
– The environment– Prioritizing conservation– Balancing societal and human needs
What is the impact of human activities?
Working individually:
Write a short passage explaining how resource depletion is connected to human activities.
Consider focusing on:• Needs and role of local communities• Dilemmas such as food or jobs versus exploiting resources• Large-scale activities such as industrial fisheries
With your group:
Explore online resources to describe the relationship between human population and fish stocks and meat production.
Be sure to:• Obtain data on:
– Human population increase– Decline of fish stocks– Increase in global meat production
• Describe potential sources of error or inaccuracy in estimating correlations
Correlation of Population and Food Production
Correlation of Population and Food Production: Resources
Impacts on Communities
With your group:
Choose a case study of food resource decline and research the impact on local communities.
Examples of possible case studies:• Collapse of North Atlantic cod fishery • Destruction of tropical rainforests • Overgrazing in North Africa’s Sahel region
The greatest danger to
our future is
apathy.

Brainstorm!
Your mission (should you choose to accept it)!
Create a list of activities that publicize and educate about dietary choices.
Ensure that your activities:• Are feasible and realistic• Do not require funding• Ideally could be conducted in a class setting
Know the
carbon cost of
what you eat.
Eating For Wildlife
• Eat less meat • Eat seasonally and
locally• Go vegetarian or vegan• Eat organic• Eat sustainable
seafood• Drink filtered tap
water• Choose shark-free tuna• Avoid shark fins and
oils• Vote with your wallet
and your fork
Tragedy of the Commons
If time allows:
Investigate the concept of The Tragedy of the Commons.• Write a passage describing how this concept explains
environmental problems such as overfishing.

Evaluation
1. Write a short passage describing the relationship between food production and extinction.
2. Which of the following have the greatest impact on food production: habitat loss, carbon dioxide emissions, pollution, decline of crop diversity, or soil erosion? Justify your answer.
3. Explain how human population increase and consumption has led to the decline of fish stocks and increased meat production.
4. Compare and contrast different types of food production in their impacts on extinction and climate.
